STEAM-GENERATOR SPECIFICATION forming part of Letters Patent No.350,202, dated October 5, 1886.

Application filed April 20, 1886. Serial No.199,455. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM E. KELLY, of New Brunswick,in the county ofMiddlesex and State of New Jersey, have invented a certain new anduseful Improvement in Steam- Generators, of which the following is aspecication.

I will describe a steam-generator embodying my improvement, and thenpoint out the various features of the improvement in claims.

In the accompanying drawings, Figure l is a Vertical longitudinalsection of a steam-generator embodying my improvement. Fig. 2 is atransverse vertical section of a portion of the generator, the sectionbeing taken close to the front end. Fig. 3 is a transverse section ofcertain parts, the section being taken as indicated by the dotted line ww, Fig. l. Fig. 4 is a front view of a combined header and saddle uponwhich the front end of the steam and water drum of the generator rests,the latter part being shown in section. Fig. 5 is an inverted plan ofthis combined header and saddle, a portion being shown in section. Fig.6 is a transverse vertical section of this com- Fig. 6* is a front viewof a group of headers. Fig. 7 is an elevation of a group of sections ofa dame-plate. Fig. 7* is a perspective view of the boilertubes, showingthe form of the headers and mode oi connecting up the pipes, togetherwith the form and arrangement of the dame-plates. Fig. 8 is a verticalsection of certain sections of this flame-plate, the section being takenas indicated by the dotted line x x, Fig. 7. Fig. 9 is an elevation of amodified section of a name-plate. Fig. l0 is avertical section of anozzle or `nipple upon which a safety-valve is fitted, and by whichwater gage pipes are coupled together and steam pressure gagepipes areunited. Fig. 11 is a horizontal section of the said nozzle or nipple,taken at the dotted line y y, Fig. l0, and showing the same as itappears when looking upward. Fig. l2 is a vertical section of the samenozzle or nipple modified so as not to serve as a coupling for thesteam-pressure gage-pipes, but merely as a coupling for the water-gagepipes. Fig. 13 is a horizontal section of this modified nozzle ornipple, taken on the plane of the dotted line z z, Fig. 12, and showingthe same as it appears when looked at from below. Figs.

influence of the heat of the products of com-A bustion from a furnace.These tubes are connected at their ends to headers B, and the headers Bare united one above another and connected with a steam and water drum,C, so that water, when sufficiently heated, and steam may ascend throughthe inclined tubes, and rise through the headers B, to which the upperends of the inclined tubes are connect' ed, into the drum C, and so thatthe cooler water will descend from the drum C into and through theheaders to which the lower ends of the inclined tubes are connected, andpass from these headers into the inclined tubes.

D designates a combined header and saddle placed under the forward endof the steam and water drums C, and affording ameans of communicationbetween the inclined tubes and the drum. This saddle will be casthollow, and preferably provided, for the purpose of increasing itsstrength,with vertical partitions a, dividing it into compartments,communication between the compartments being afforded by means ofopenings bin the partitions. The upper row of headers B communicateswith the saddle D by means of nipples @expanded or screwed into openingsd in the lower side of the saddle D and into corresponding openings inthe upper sides of the headers. The saddle is provided with a curvediianged portion, d', upon which the drum rests,and which is riveted tothe drum. An opening, d2, in the drum affords communication between thedrum and the saddle. The saddle is provided with a conduit, D', which isclosed against the admission of steam or water from the saddle. Thisconduit may be cast in the saddle. A

pipe, D, secured near one end in a suitable opening in the conduit D',affords communication between the conduit and the interior of the drum.A pipe, D3, secured at one end in a suitable opening in the conduit Dbelow thedrum, extends outwardly, and. connects near its outer end tothe lower end of a water-gagel from the point where the saddlecommunicates.

with the drum, and hence to a point where thewater is less agitated thannear 4theopening.

. D9 designates a conduit similar to the conduit D', *and likewisearranged in the saddle D. Feed-water pipes D1 D11 communicate with thisconduit, whereby water may be fed to the drum. It is an importantfeature of this arrangement that I am not obliged to cut holes in theshell of the drum C in order to introduce any of the pipes for thewater-gage or the feed-water pipe. The cutting of such .holes is verydifficult of execution, and can seldom be done with a desireddegree ofaccuracy, and also has a tendency to weaken the shell of the drum. Byproviding the saddle D and nozzle D5, therefore, with closed conduits,

with which the pipes of the water-gage and feed-water pipe communicate,much time and labor are saved, because the conduits may be cast in thesaddle and nozzle, and the holes for the reception of the pipes may betapped before the saddle and nozzle are secured to the drum.

Ido not wish to be understood as limiting myself to the precise shape ofthe conduits D and e, nor to the particular manner of connect-ing theseveral pipes thereto, as these may of course be varied. Figs. 13, 14,and 15 illustrate `different methods of forming the, conduits e in thenozzle D5, andlikemoditications of form or even different onesl may beemployed in the saddle.

In Figs. 1', 10, and 11 I have shown ameans of 4 affordingcommunicationbetween the interior of the drum and a stean1-pressure gageE, without cutting a hole through the shell of the drum, consisting in apipe, E', communieating at one end with the steam-gage, and at the otherwith a conduit, e, in the nozzle D5, similar to the conduit e. A pipe,e?, extends from the conduit e into the interior of the drum. Fdesignates a saddle somewhat similar to the saddle D, located beneathand near the rear end of the drum and riveted to the'drum. This saddlea'ords communication with the l circulating-tubes A for the returningwater,

tubes f being connected to it and the headers B at the lower end of theinclined tubes A.

This saddle is provided, as shown, with twov be blown off. Of course,feed-Water pipes can be introduced into the saddle F, if desirable.Byriveting the saddles D and F to the drum the latter is braced andstrengthened.

Anotherimportant feature of my improvement consists in the flame-platesK K', by which the flame and products of combustion are caused to`follow a circuitous course through the circulatingtubes. Theseflame-plates are made up of sections G, whjchwill preferably whichheaders is shown in this example of my lating-tubes. I have shown thisarrangement more clearly in Figsg l and 7*; but I do not headers andAflame-plates may be used than those shown. The sections G of theamewill preferably be cast in such manner that tending about the edges,and thimbles g2 formed in suitable positions in the back, and extendingforward approximately coincident with the rim g. Pins or projectionsg3extend from ',shown, they are arranged at inclines to each other. Theymay be cast with the sections or secured therein in any suitable manner.It is intended that the space within the seclar material, s. Where suchmaterial isused the pins g? serve to retain it in position. I may,however, ill in the spaces with bricks of suitable form, which may vbedriven in or secured therein inany suitable manner. such case the pinsmight be omitted. So far as the pins g and their arrangement are con.cerned, the flame-plates might of course be of upon their rear sideswith lugs g5, through which pins or bolts 96 may be passed to securethem together when in position about the pipes. The circulating-tubesextend through the thimbles g2, which latter protect the clay within thesections from the rubbing of the tubes. It will be advantageous to,`place the dame-plate sections in position on the tubes, as shown in Fig.7 before shipment, and iill them with the clay or other materialwhen thegenerator is being depended on to bake the clay hard. The sections aresuperposed one upon the other, and do not overlap.

InFig. 9 I have shown aflame-plate section of modified form, composed ofa number of parts, s', securedtogether and held in place by bolts si.AAlthough this name-plate is made up of a number of parts, it isundivided, said parts being connected rigidly together, so as conform totheform of the headers B, each of improvement as receiving three of thecireuf plates aie made of iron and are hollow. They the back toward thefront of the sections. As

any desired form. The sections are provided erected. The heat of thefurnace may then be r Another feature of my improvement consists in thechannel-irons J above the drum, and thneJ mode of arranging the hooks bywhich the drum is supported from the channel-irons. The channel-irons,it will be observed, have flanges j' upon their lower sides,which extendinwardly or toward each other, whereby a considerable space is leftbetween the channel-irons. By thus forming the channel-irons I amenabled to use but a single hook, J', with each set of channel-irons,which hook is inclosed within the space between the channel-irons,thereby enabling the channel-irons to be brought much closer to the drumthan has heretofore been possible when single hooks have been used. Thehooks J engage with iron loops J '1, riveted to the drum. The height ofthe generator is therefore materially reduced, which is a desirablefeature.

Instead of the conduits e e being arranged in a safety-Valve, they maybe arranged in any other suitable outlet-nozzle.

Vhat I claim as my invention, and desire to secure by Letters Patent,is-
